The Chronicle of Matthew of Edessa is a valuable source for the history of the Middle East in the 10th-12th centuries. Matthew's work describes the period from 952 to 1129. A continuation by Gregory the Priest describes events from 1137 to 1162. Western scholars have used the Chronicle primarily for its unique information on the Crusades. It contains, additionally, invaluable information on Byzantium, the Arabs, Saljuqs, Persians, and especially the Armenians, both secular and clerical, both lords and louts. Along with this, Matthew describes such diverse phenomena as urban mobs, siege warfare, and confessional disputes, and he presents a welter of remarkable material of interest to many disciplines, including folklore and anthropology. Attached to the document are:  two groups of maps, by renowned cartographers; chronological tables; a multilingual HTML version; and links to additional resources. Translated by Robert Bedrosian from the Classical Armenian edition of Vagharshapat/Ejmiatsin, 1898, in 158 bookmarked and searchable pdf pages.
